What do Flock cameras do?
Every time a vehicle passes, the camera:
| Action | Detail |
|---|---|
| Reads the plate | Photographs and recognizes the license plate characters |
| Logs it | Records plate + timestamp + location |
| Adds vehicle details | Make, model, color, distinguishing features |
| Checks databases | Alerts if the plate matches a stolen car, wanted plate or AMBER alert |
Even a "clean" plate gets logged. That record is kept for a period set by local policy and state law — see how long plate data is stored.
What are Flock cameras used for?
- Crime response — finding stolen vehicles and wanted plates quickly
- AMBER alerts — matching plates against missing-person alerts
- Investigations — reconstructing where a vehicle traveled
- Community surveillance — HOAs and gated communities log entry/exit
How they work (the short version)
Capture → recognize → log → match. It's the same loop as every ALPR — for the full step-by-step, see how Flock cameras work, or the industry-generic how ALPR works.
Why they're controversial
Because every passing vehicle is logged — not just suspects — and because the records can be kept for long periods and shared across agencies. The backlash is documented: 23+ jurisdictions have ended Flock contracts (live tracker). See 6 reasons Flock cameras are controversial.
